Hey all..... In the 1st week of flowering and just woke up to find 1 of 2 plants drooping. Watered 2 days ago and still has weight to the pot. If it is over watered do I just leave it to dry out?? IMG_20190725_101137.jpg

I see heat stress. Let it just ride for a while. What is the RH there? How high is that light?

Hey.... Humidity is around 45...and temp can be upto 37 Celsius. We are having a little heat wave at the minute.
I have raised the light to near a metre. It sprung back yesterday then droopy again this morning.
Sprayed and watered again and looking good but sure will go backwards by the morning again

It’s your temperature. They have trouble transpiring with a full load of water. Just don’t overwater.

Perfect example of why VPD is important.
Do not spray them with water while the lights are on.
In times of high heat raising the humidity will help and in week 1 of flowering I would say your humidity is to low to begin with. 55-60% would help alleviate some of the stress you don't have buds yet and no need to be that restrictive on humidity this early in flower

What is vpd? Total newbie here. Again hard to heighten humidity with temps so high at the minute

Vapor pressure deficit. But don't go running out and grab a chart and apply it. I would suggest a good amount of research on how to use it properly because if not used properly people generally get mold issues and if you can't control the environment your better off running lower humidity than listed by VPD due to spikes in nighttime humidity

With a higher RH, optimal air flow is a must to avoid mold

Like Aqua mentioned, make sure you don't get sudden spikes in your RH. Temp & RH, especially between lights on/off transitions

From what I've read PM happens from huge swings from not monitoring/managing RH
